of the 69 kV system that serves the pumping stations on the Contra Costa Canal. As for the pylons of the PG&E and PacifiCorp Round Mountain-Malin parallel lines, the PG&E line uses the same tower type as the PG&E Table Mountain-Round Mountain 500 kV segment does. The PacifiCorp 500 kV line uses a pylon that looks similar to the pylon used in WAPA's Olinda-Captain Jack segment. Visual reference Problems Since TANC's Captain Jack-Olinda 500 kV wire rises to almost as the line crosses the rugged mountains near Grizzly Peak, that section of 500 kV line is covered with large amounts of snow during the winter. Despite its location far from the Pacific Ocean, of snow can accumulate near Grizzly Peak's -summit. The extreme snowfall there can cause ice and snow to accumulate on the insulators and the wires and sometimes lead to power outages when the wires snap in these extreme conditions. This high-elevation segment of 500 kV line is also said to be problematic.
